Get simple response from SOAP service with classic asp - soap

Question

I have been tasked with obtaining a response from a SOAP request, using classic asp. The request is about as basic as it gets - I just need to fire off 3 parameters to a web service URL and write out the response (which is in simple plain text format). I've checked the service using a couple of SOAP testing utilities and it outputs the response fine.
I've also read about 10 different tutorials on consuming SOAP feeds in classic ASP, but none of them seem to work at all.
The latest one I'm trying has given me the following code:
<%
Set oXmlHTTP = CreateObject("Microsoft.XMLHTTP")
oXmlHTTP.Open "POST", "http://www.webservicehost.co.uk/B2bservice.asmx?wsdl", False
oXmlHTTP.setRequestHeader "Content-Type", "application/soap+xml; charset=utf-8"
oXmlHTTP.setRequestHeader "SOAPAction", "http://ourNameSpace/ourFunction"
SOAPRequest = _
"<?xml version=""1.0"" encoding=""utf-8""?>" &_
"<soap12:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap12=""http://www.w3.org/2003/05/soap-envelope"">" &_
"<soap12:Body>" &_
"<ourFunction xmlns=""http://ourNameSpace/"">" &_
"<Ccode>OurCode</Ccode>" &_
"<Pword>1d2s45a</Pword>" &_
"<OrderNo>9876</OrderNo>" &_
"</ourFunction>" &_
"</soap12:Body>" &_
"</soap12:Envelope>"
oXmlHTTP.send SOAPRequest
response.write oXmlHTTP.responseText
%>
I have all the correct values for the POST URL, the Ccode, Pword and OrderNo variables, but have no idea what to use for the "SoapAction" or values. As a result, when I run the page I just get an error:
soap:SenderUnable to handle request without a valid action parameter. Please supply a valid soap action.
Can anyone suggest what to use for the SoapAction and ourFunction xmlns values?
Many thanks for any pointers...

Answer 1

your code should work ok with a few changes
<%
Response.Write "<br>START<hr>"
Set oXmlHTTP = CreateObject("Microsoft.XMLHTTP")
oXmlHTTP.Open "POST", "http://www.crusaderb2b.co.uk/b2bservice.asmx", False
oXmlHTTP.setRequestHeader "Content-Type", "text/xml; charset=utf-8"
oXmlHTTP.setRequestHeader "SOAPAction", "http://crusaderb2b.co.uk/TrackingId"
SOAPRequest = _
"<?xml version=""1.0"" encoding=""utf-8""?>" &_
"<soap12:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap12=""http://www.w3.org/2003/05/soap-envelope"">" &_
"<soap12:Body>" &_
"<ourFunction xmlns=""http://ourNameSpace/"">" &_
"<Ccode>OurCode</Ccode>" &_
"<Pword>1d2s45a</Pword>" &_
"<OrderNo>9876</OrderNo>" &_
"</ourFunction>" &_
"</soap12:Body>" &_
"</soap12:Envelope>"
oXmlHTTP.send SOAPRequest
Response.Write oXmlHTTP.responseText
Response.Write "<br>END<hr>"
%>
changes are
remove ?wdsl
change content type
method call needs to be the same server of the webservice as it's the method name
added
I changed the code as you provided the Web Service. All you need you have in the service page as:
